it is thought that some people's right side of their brain is more active than their left and some people's left side of their brain is more active than their right. if this is thought to be true, does it have anything to do with which testicle we originated from?

right handed people have a dominant left hemisphere and left handed people have a dominant right hemisphere. It has nothing to do with what testicle you come from, since both produce identical sperm cells(identical from this point of view, at least...)

is it possible for a right-handed person to open,expand, and activate his/her right hemisphere of their brain to try to be equal with their dominant hemisphere, or is he/she just basically thinking that he/she is thinking more with their right hemisphere of their brain?

I noticed that people who use their left hand are better in math generaly.
at least in my family.
